Consider the cause of the tearing. If the eyes feel dry and burn and then begin to tear, consider artificial tears before tearing occurs. This prevents the reflex tearing.

If the eyes are itchy and uncomfortable consider allergy as a cause. Occasionally topical and over the counter antihistamines can be useful. If the eyes have a mucous discharge or are red, consider a blocked tear duct or eyelid problem.

Tearing is not an emergency, but can be very annoying and usually can be treated.

Intervention:

Once the symptoms are explained, the cause is usually clear. Treatment can include artificial tears, topical antihistamines antibiotics or even surgery.

If a blockage of the tear system is possible, a probe is inserted into the tear drainage system. This is painless. If a blockage is present surgery is usually necessary to correct the problem. Improper eyelid position can also be fixed with minor surgery.
